With reference now to the drawing figures, wherein like reference numbers represent corresponding parts throughout the several views, FIGS. 1-16 show various aspects, components and modes of use of a foldable or rollable play gym 10 according to an example embodiment of the invention. Generally, the play gym 10 includes a play mat 20 and a bar or toy bar 50. The play gym 10 is convertible between a use configuration, shown in FIG. 1 and a folded, storage configuration, shown in FIG. 16. In example embodiments, the play gym 10 can fold down to a minimal size for storage and/or travel. Generally, the mat 20 is configured to fold, roll, or collapse and the toy bar 50 is foldable or collapsible. In example embodiments, the toy bar 50 is releasably attachable to the mat 20. In other embodiments, the toy bar 50 can be permanently attached to the mat 20.

In the use configuration, shown in FIGS. 1 and 2, the folding mat 20 is configured to rest on a support surface, such as the floor, ground, or another substantially horizontal surface. The bottom surface of the mat 20 is configured to contact the support surface. The top surface of the mat 20 is configured to engage or support the child. In the depicted embodiments, the mat 20 has a rectangular shape having two sides 22, and two ends 24. As best seen in FIG. 2, the sides 22 of the mat 20 are generally longer than the ends of the mat 24, making the length of the mat longer than the width of the mat. In other embodiments, the mat 20 can be any shape suitable for providing a comfortable surface for an infant or child including circular, square, oval or polygonal shaped.

In example embodiments, the mat 20 is formed from a shell 26 that surrounds and contains a compressible fill material. The compressible fill material is designed to provide additional comfort and support to the infant. In alternate embodiments, the mat is formed of a padded polyethylene material that is lightweight and waterproof or water resistant. The mat 20 can be formed from a series of panels 28 hingedly connected to one another. In the depicted embodiment, the panels 28 are separated by hinges or seams 30 in the shell 26 of the mat 20. The seams 30 can be formed by stitching, heat pressing, or otherwise attaching the bottom surface of the shell 22 to the top surface of the shell. The seams 30 help to create creases or fold lines for folding the mat 20 into a compact configuration for travel or storage. In the depicted embodiment, the seams 30 extend horizontally across the mat 20 from side 22 to side. In other embodiments, other configurations of panels and seams can be used to fold the mat 20. For example, the seams 30 can extend vertically on the mat from end 24 to end or the seams can be configured to form polygonal panels.

In example embodiments, the fill material is formed from a substantially resilient material. The resilient fill material can be formed from foam, polyester fill, batting, or another conventional resilient and compressible material for providing a cushioning effect. The mat shell 26 is generally formed from a flexible, non-toxic fabric such as polyvinyl chloride, polyethylene, or taffeta. In example embodiments, the shell 26 is formed from a water-resistant fabric such as taffeta or a laminate material. In other embodiments, the shell 26 material can be treated to make said fabric water resistant. The shell 26 can include one or more designs, patterns, colors, or tactile combinations to provide stimulation for the child. In other embodiments, the mat 20 includes a removable cover configured to surround the shell 26 of the mat. The cover can be formed of a similar material to the above-described shell. The cover can be removed to be washed.

The toy bar 50 is designed to be held in tension when attached to the play mat 20, but fold when it is detached or partially detached from the mat. In alternate embodiments, the toy bar can be configured to fold when attached to the mat. As shown in FIGS. 1 and 2, the toy bar 50 is arch-shaped having a first end 52 and a second end 54. In alternate embodiments, the toy bar 50 can be any suitably shaped arch (e.g. triangular, flat, camber top, parabolic, elliptical, lancet, pointed, etc.). Although a single toy bar is shown, one or more toy bars can be coupled to the mat 20. For example, two toy bars can be coupled at different points along the mat 20 to run parallel or perpendicular to each other. In the example embodiment, the toy bar 50 includes a plurality of panels 56 that are coupled together to provide tension when the toy bar 50 is in the arched use position, as shown in FIGS. 1 and 2, but allow the toy bar to fold into the storage position, as shown in FIG. 12. In the depicted embodiment, the toy bar 50 includes three panels 56. In other embodiments, fewer or more panels can be used. In example embodiments, the panels 56 are coupled to one another in an overlapping configuration to provide tension in the arched use configuration. In other embodiments, the panels are coupled end-to-end to create the arched configuration. In the depicted embodiments, the panels 56 have a rectangular shape. In other embodiments, differently shaped panels can be used.

As shown in FIGS. 3-5, the overlapping panel design allows the toy bar 50 to be held in tension when the ends 52, 54 are attached to the mat 20, but will fold when one or both of the ends are detached from the mat. Each panel 56, 56′, 56″ includes a first end 58, 58′, 58″ and a second end 60, 60′, 60″. In example embodiments, the panels are interchangeable. In the depicted embodiment, the panels 56, 56′, 56″ have generally the same length. In alternate embodiments, the length of the panels can differ. For example, one or more of the panels can be wide enough to provide a canopy for shielding the sun from an infant on the mat. The first end 58 of the first panel 56 is releasably fastened to a side 22 of the mat. The second end 60 of the first panel 56 is pivotally coupled to the top surface of the second panel 56′ at a point offset a distance D from its first end 58′. In example embodiments, the offset distance D is between about 1 inch and about 2 inches to create tension in the arch structure, described in detail below. In example embodiments, the panels 56, 56′, 56″ are permanently or semi-permanently coupled together using attachment mechanisms such as stitching, adhesive, or a hinge mechanism. The panels 56, 56′, 56″ can be sewn together to form a fabric hinge. The first end 58′ of the second panel 56′ is free to rotate about the coupling between the second end 60 of the first panel 58 and the second panel. The second end 60′ of the second panel 56′ is attached to the top of the third panel 56″ at a point a distance D from its first end 58″. The first end 58″ of the third panel 56″ is free to rotate about the coupling between the second end 60′ of the second panel 58′ and the third panel. The second end 60″ of the third panel 56″ is releasably attachable to the side 22 of the mat 20 opposite the first end 58 of the first panel 56.

When both ends 52, 54 of the toy bar 50 are attached to the sides 22 of the mat 20, the first ends 58′, 58″ of the second 56′ and third 56″ panel are forced into engagement with the bottom of the first 56 and second panel 56′, respectively. As the panels 56, 56′, 56″ bend, the first ends 58′, 58″ of the second 56′ and third 56″ panel impart an upward force, creating tension in the resulting arch structure. When an end 52, 54 of the toy bar 50 is decoupled from the mat 20, the tension is released, and the toy bar is able to fold, for example by rotating the second end 60″ of the third panel 58″ toward the first 56 and second 56″ panel. The panels 56, 56′, 56″ are pivoted such that the toy bar 50 folds into a flat, compact configuration for travel or storage. In the storage position, the panels 56, 56′, 56″ are stacked such that they substantially align on top of one another.

In example embodiments, the toy bar 50 can also be releasably coupled along the outer periphery of the mat 20 to create a side wall. The toy bar 50 is positioned such that its sides are coupled to the sides 22 and/or ends 24 of the mat 20. The toy bar 50 extends upward from the edge of the mat 20 perpendicular to the support surface. In example embodiments, the toy bar 50 can be used as a wall that surrounds the outer periphery of the mat. In this wall configuration, the toy bar 50 can contain a child or infant on the mat 20. The wall configuration can be also be used to contain toys within the boundaries of the mat, for example, to use the foldable play gym 10 as a ball pit. In other embodiments, the toy bar 50 can extend around a portion of the periphery of the mat.

In alternate embodiments, the attachments between the panels are releasable, in which case they can be fixed rather than pivotal. In this embodiment, the panels are releasably coupled together by one or more fasteners such as hooks, ties, buckles, snaps, buttons, hook-and-loop fasteners, or other attachment means. The panels are detached from one another to fold the toy bar to the storage position. In alternate embodiments, the toy bar 50 may comprise thin, metal bistable spring inserts that provide support and structure to the toy bar.

In example embodiments, the panels 56 are formed from a flexible insert surrounded by an outer shell. The flexible insert can be formed from one or more sheets of polypropylene. According to example embodiments, the thickness of the polypropylene sheet inserts is between about 1 mm and 10 mm, more preferably between 2 mm and 8 mm, for example about 2 mm. The sheet inserts are dimensioned to bend to form the arch-shaped toy bar while being rigid enough to provide tension. The outer shell can be formed from a fabric material such as polyvinyl chloride, polyethylene, or taffeta.

The play gym 10 generally includes primary fastening mechanisms 80, 80′ configured to attach the ends 52, 54 of the toy bar 50 to the sides 22 of the mat. In the depicted embodiment, the fastening mechanism 80 includes a female sleeve 82, positioned on the end of the toy bar 50, and a male rod 84 positioned on the side 22 of the mat 20. As best seen in FIGS. 8-10, the male rod 84 is laterally inserted into the female sleeve 84 to releasably couple the end 52 of the toy bar 50 to the mat 20.
